In 1974, the City Centre Place office tower (now Oxford Tower) was completed within the larger Edmonton Centre development; TD Tower was added in 1976. In 1978, Oxford Tower (now 101st Tower) and the Sutton Place Hotel were built on the north edge of the site. Across the street a new development was in planning. The original plan for what was then called Eaton's Centre, announced in 1980, called for several large office and apartment towers. None of the originally designed five towers was ever built but the multi-level Eaton's Centre mall and the Delta Edmonton Centre Suite Hotel were salvaged from the project.
After the demise of the Eaton's department store in 1999, Eaton's Centre and Edmonton Centre, formerly two independent malls, were redeveloped into one shopping complex connected by a newer and larger pedestrian bridge spanning 101 Street (that itself contains a number of shops).
On June 27, 2013, Empire Theatres announced that it would be selling this theatre location along with 22 others in Western Canada and Ontario to Landmark Cinemas. On October 29, 2013, Empire Theatres closed and reopened as Landmark Cinemas on October 31, 2013.
On November 18, 2015, Edmonton City Centre announced that it planned to relocate and significantly upgrade its food court as part of a $41.3-million redevelopment investment that would revitalize the entire retail experience of the downtown property. Construction was scheduled to begin in November 2015. The new food court was expected to open in November 2016, and the property revitalization project would be complete by November 2017.
ECC is home to four office towers: two (TD Tower, City Centre Place) are connected to the mall, the third, (Bell Tower), is located across the street, and the fourth, (101 Street Tower), is located in the lobby of the Sutton Place Hotel. These towers range from 23 to 32 storeys in height and house many different businesses.
